By taking a bearing from TWO VORs simultaneously, the distance to each can be computed. That's why planes have two VOR receivers and instruments.

Two VOR stations will give you a fix, but since GPS took over from legacy RNAV, that’s now rarely used operationally in the US.

More common is to use Nav2 tuned to a VOR to find an intersection on the arrival and Nav 1 to fly the final (ILS/LOC/VOR).
